sys-admin
Ah, a former receptionist who's been cross-trained. That's nice. (At least that's how we grew them; the people who already had CS degrees seemed to get bored quickly, whereas the receptionists could use it as a stepping-stone toward something else more interesting.)
Yet again, something which all too many believe is difficult and arcane enough to require several years to learn, when all it takes is a few weeks.
Now, security specialist is another matter. That takes both a knack (to be able to anticipate the malefactors' likely thinking), and a bit of learning to know about sys and app and network design and hence the likeliest vulnerabilities.
